<P>PROBLEM TO BE SOLVED: To provide an imaging device capable of obtaining an image with low noise without narrowing a dynamic range of a circuit of an imaging element due to the offset of a dark current that occurs in each pixel of the imaging element. <P>SOLUTION: The imaging device includes an imaging element having a light-receiving unit 101 in which a plurality of pixels are arranged in the row and column directions and which generates charges in accordance with an amount of incident light. The imaging element has a column correction value calculating circuit 109 that generates noise data for each column in accordance with the output of a specific pixel of the light-receiving unit 101, a gain amplifier that is arranged for each column of the light-receiving unit 101 and subtracts a reference signal from a signal of the light-receiving unit 101, and a reference potential supply circuit 109 that supplies the reference signal to each column in accordance with the noise data. <P>COPYRIGHT: (C)2010,JPO&INPIT |
